A rare piece of probably unknown (to most) Apple history: the first portable Mac - which wasn't the Mac Portable and wasn't built by Apple. "I'd never heard of the Walkmac, which wasn't built by Apple but by electronics pioneer Chuck Colby, who founded Colby Systems in 1982. The Apple-sanctioned model you see here was 'modded' around a stock Mac SE motherboard and hit the market in 1987, two years before Apple put out its Macintosh Portable in 1989 for $7,300. Subsequent Colby models were built around the SE-30 motherboard and had an integrated keyboard (that black mat in the picture above is a mouse pad)."
